2. OVERVIEW/ SYSTEM DESCRIPTION
2.1 General System Description
The Weehawken tunnel radio system is designed to amplify various bands of radio frequencies,
in either channelised or band selective modes. This unit amplifies all the RF bands to the ‘River
Portal’ area in a band-selective mode with AGC in the uplink direction. All the hardware is
built into a standard environmentally protected cabinet which has an IP rating of 65.
The system described in this document is ‘stand-alone’ and needs no other equipment apart
from a +12V DC power supply. Every active module in the entire system has a dedicated alarm
and these are series wired within the unit to a relay which gives a volt-free output pair which is
wired to a ‘krone-block’ termination and ultimately to a pair of wires in an external port
connector (alarm connector, pins 1 & 2).
